Abstract

Se describe un método para controlar la operación de un impulsor de un dispositivo de infusión ambulatorio (2), en el que el impulsor del dispositivo de infusión ambulatorio (2) incluye un mando de husillo (2), con un motor de velocidad gradual (21), y un codificador rotativo (23) en acoplamiento operativo con la pieza impulsora; el método incluye ejecutar en forma reiterada una secuencia de controles del impulsor, donde la secuencia de controles del impulsor comprende lo siguiente: a) accionar el motor de velocidad gradual (21) para que ejecute un número de pasos solicitados en la secuencia actual de controles del impulsor; b) recibir la posición de la pieza impulsora, donde la posición de la pieza impulsora es indicativa de una posición real de la pieza impulsora luego del accionamiento; c) calcular, a partir de la posición de la pieza impulsora y del número de pasos solicitados, un número de pasos frustrados como un desvío entre el número de pasos solicitados y el número de pasos ejecutados en la secuencia actual de controles del impulsor; d) determinar, basándose en una evaluación estadística de la distribución en el tiempo del número de pasos frustrados, contra un historial de secuencias de control del impulsor, si el impulsor (2) está bloqueado. El método incluye, además, generar una señal de alarma de bloqueo si se determina que el impulsor está bloqueado.A method for controlling the operation of a driver of an ambulatory infusion device (2) is described, in which the driver of the ambulatory infusion device (2) includes a spindle drive (2), with a stepper motor ( 21), and a rotary encoder (23) in operative engagement with the driver; The method includes repeatedly executing a sequence of impeller controls, where the sequence of impeller controls comprises the following: a) driving the stepper motor (21) to execute a number of steps requested in the current sequence of controls of the impeller; b) receiving the position of the driver, where the position of the driver is indicative of an actual position of the driver after actuation; c) calculating, from the position of the driver and the number of steps requested, a number of steps missed as a deviation between the number of steps requested and the number of steps executed in the current sequence of driver controls; d) determining, based on a statistical evaluation of the distribution over time of the number of missed steps, against a history of impeller control sequences, whether the impeller (2) is blocked. The method further includes generating a blocking alarm signal if the impeller is determined to be blocked.
